The invention relates to a circuit breaker for mounting on a power circuit, in particular to a smart fuseless switch which can be automatically cut off according to environmental conditions and has a replaceable module.

According to the current situation, most of the power transmission is transmitted to the relay station via a power plant (power generation equipment), and then enters the designated room one by one according to the power distribution system. When entering the room, it will pass through the equipment of multiple circuit breakers (also known as the main switch). In addition to controlling whether the current passes, it can also automatically jump off when the current is too large, so as to protect the connected electrical appliances.

However, often in the event of a natural disaster such as an earthquake, some electrical appliances may cause the wires to come out during the process of falling, which may cause the problem of wire fire, resulting in more serious losses.

The connecting base is electrically connected to the electromagnetic trip unit. The vibration detecting module is inserted into the connecting base. When the vibration detecting module detects that the vibration level is higher than a preset value, the electromagnetic trip device is triggered to push the mobile contactor to disconnect the line via the connecting base.

When the vibration detecting module detects that the vibration reaches a preset level, it will send a signal to control the electromagnetic tripping device to be transmitted through the connecting seat, so that the mobile contactor stops disconnecting the line, and the power will not pass into the house to reach The effect of automatic power off. At the same time, the connector of the creation can be placed at will, which overcomes the problem that the special circuit breaker cannot be installed in the old main switch box, and the vibration detection module can be directly replaced without disassembling the circuit breaker, even if it is other When the external force causes the vibration detection module to be damaged, only the vibration detection module needs to be replaced.

Preferably, a state detection module and a signal transmission module are further disposed. The state detection module can detect voltage information or current information between the first circuit connection end and the second circuit connection end. Or temperature information, the signal transmission module is used to transmit voltage information or current information or temperature information or receive instructions. It can be used for external data collection and monitoring to improve safety.

Preferably, the connecting seat and the vibration detecting module are provided with corresponding snap mechanisms. Therefore, the connection seat and the vibration detecting module can be stably combined.

Preferably, the connector is adjacent to the smart fuseless switch.

The invention further provides a smart fuseless switch set, which comprises a control unit, a smart fusible switch as described above and a plurality of automatic no-fuse switches.

The signal transmission module is connected to the control unit via the signal transmission module. Moreover, the automatic fuseless switch includes a moving contactor and a switch. The moving contactor is linearly connected between a first circuit connection end and a second circuit connection end. The switch is connected to the moving contactor via a mechanism, and an electromagnetic tripper is connected to the moving contactor, and the moving contactor is moved to move between the first circuit connecting end and the second circuit connecting end.

This embodiment is a smart fuseless switch 1 which can detect vibration. When the measured data is higher than a predetermined value, the circuit will be disconnected and the power transmission will be stopped to ensure that the indoors will not be closed. A situation in which an unexpected situation causes the wire to escape. Moreover, the present embodiment overcomes the shortcomings of the prior art. Once the current is damaged due to the sudden increase of current, the module can be continuously detected and protected without replacing the entire circuit breaker.

As shown in FIG. 1 , the smart fuseless switch 1 of the present embodiment includes a mobile contactor 11 , a switch 12 , an electromagnetic trip 13 , a connector 14 and a vibration detecting module 15 . .

When the mobile contactor 11 is separated from the first circuit connection end 111 or the second circuit connection end 112 to form an open circuit, power will not enter the room.

The switch 12 is connected to a moving contactor 11 via a mechanism, and the electromagnetic trip unit 13 is coupled to the moving contactor 11 and can drive the moving contactor 11 to move. Therefore, the user can manually switch the position of the mobile contactor 11 via the switch 12. When the electromagnetic release 13 receives the indication, the electromagnetic release 13 automatically disengages from the original position due to the electromagnetic force becoming larger, and the mobile contactor 11 is driven. Leaving a position connected to the first circuit connection end 111 or the second circuit connection end 112 causes the first circuit connection end 111 or the second circuit connection end 112 to form an open circuit to stop the input of power.

When the disaster occurs, the magnetic force of the electromagnet in the electromagnetic trip 13 is changed to achieve the purpose of trigger driving.

The vibration detecting module 15 is movably inserted into the connecting base 14 and connected to the connecting base 14 to transmit the command sent by the vibration detecting module 15 and obtain power as the vibration detecting module 15 The related medium flowing through the information, for example, a sensor connected to the signal of the connector 14 is mounted on the power system, and the vibration detecting module 15 reads the data through the connecting base 14. Since the connection between the connector 14 and the vibration detecting module 15 is a loop of the prior art, whether it is a wired or wireless transmission method or a method of connecting the male and female signal connectors, the vibration detection is performed. The manner in which the module 15 is connected to the connector 14.

In the above manner, when the vibration detecting module 15 is damaged due to the sudden increase of current, the broken vibration can be removed, and a new vibration detecting module 15 can be directly replaced, thereby greatly reducing the difficulty of maintenance.

Further, the state detecting module 16 and the signal transmitting module 17 are connected to each other, and the state detecting module 16 is configured to detect the first circuit connecting end 111 and the second circuit connecting end. Voltage information or current information or temperature information between 112, the signal transmission module The 17 series is used to transmit voltage information or current information or temperature information or receive commands. It can be used for data transmission using PLC technology (Power Line Communication, PLC for short). To perform more precise control. Through the collection of information, when the voltage information or current information or temperature information is different, although it is not immediately cut off, it can take the initiative to repair the service, and actively carry out maintenance before the problem occurs, to minimize the damage.

In addition, in order to make the connection between the connector 14 and the vibration detecting module 15 stable, a corresponding latching mechanism can be disposed, and the connecting seat 14 and the vibration detecting module 15 can be fixed to each other to increase the overall position. stable. Since the buckle mechanism can form a wide variety of aspects, it is a part of the prior art, and those having ordinary knowledge in the art can know without any difference, and thus will not be further described herein.

The intelligent fuseless switch group 2 can be used in the main switch box. Since the indoor distribution line is distributed, the load of each sub-switch will be evenly distributed. At the same time, some household appliances that need to use high current will be separated. If an earthquake occurs, the sub-switch connected to the high current can be automatically turned off after a few seconds of shaking through the setting of the default value, so as to avoid turning off the indoor lighting system when the house has not left the house at the beginning of the earthquake. , leading to a dilemma that cannot escape in the dark. Furthermore, the control unit 21 can be controlled via the network.
